ICSI or IVF: Babies born from frozen embryos do just as well
Analysis of the longest running ICSI programme in the United States has found reassuring evidence that babies born from frozen embryos fertilised via ICSI (intracytoplasmic sperm injection) do just as well as those born from frozen embryos fertilised via standard IVF treatment. view more (2009-06-30)
Possible evidence of cell division, differentiation found in oldest known embryo fossils
A group of 15 scientists from five countries has discovered evidence of cell differentiation in fossil embryos that are more than 550 million years old. view more (2006-10-13)
Scientists prove that disputed Korean stem cell line comes from an unfertilized egg and not cloning
Can a genetic signature identify the origin of a human stem cell line? Scientists report that a widely available method for comprehensive genetic analysis can help distinguish the type of human embryo that stem cells come from. view more (2007-08-03)
Italy now faces worldwide storm of protest over fertility proposals
Italian legislators now face worldwide condemnation by fertility experts for IVF proposals that could encourage multiple pregnancies and put babies at risk. The International Federation of Fertility Societies (IFFS) has added its voice to that of the European Society of Human Reproduction and Embryology, who have already described the proposals as... view more...

Parthenogenetic stem cells don`t solve embryo ethical problems
The isolation by Advanced Cell Technologies of primate stem cells derived from parthenogenetic embryos represents a significant technical development, but not the ethical breakthrough which the paper hopes for. Indeed it raises some disturbing ethical issues. view more (2002-02-01)
With few factors, adult cells take on character of embryonic stem cells
With the introduction of just four factors, researchers have successfully induced differentiated cells taken from mouse embryos or adult mice to behave like embryonic stem cells. The researchers reported their findings in an immediate early publication of the journal Cell. view more (2006-08-11)
Earliest embryos ever discovered provide clues to dinosaur evolution, parenting
The embryos of a long-necked, herbivorous dinosaur are the earliest ever recorded for any terrestrial vertebrate and point to how primitive dinosaurs evolved into the largest animals ever to walk on earth. view more (2005-07-29)

IVF insurance coverage yields fewer multiple births, Yale researchers find
The proportion of in vitro fertilization (IVF) multiple births was lower in the eight states that provide insurance coverage for couples seeking IVF treatment, primarily due to fewer embryos transferred per cycle. view more (2009-10-21)
Statement from the European Life Sciences Group
The promises and concerns engendered by stem cell research triggered debate world-wide. European citizens realise the significance of these issues and expect guidance to deal with them. The European Life Sciences Group thanks the European Commission and the European Commissioner for Research, Philippe Busquin, for arranging such a stimulating... view more... (2001-12-19)
Researchers urge caution over using ginseng in early pregnancy
Researchers from Hong Kong have warned that women should be cautious about using the herbal remedy ginseng in the early stages of pregnancy. They have found evidence that ginsenoside Rb1 - one of the principal active components of ginseng - can cause abnormalities in rat embryos. Their research is published today (Thursday 25 September) in... view more... (2003-09-21)
Female Sterility And Local Immunity
Extracorporal fertilisation applied to sterility treatment has become not only a rescue for a lot of women, but also a convenient research method for physicians. The method can help detect previously unknown reasons for female sterility. The number of sterile married couple is growing worldwide: 20 to 30 percent of sterility cases are caused by... view more... (2004-04-16)
ISU researchers working to develop, market embryonic test for bovine genetics
Looking at the genetic makeup of cattle to determine their value is nothing new. view more (2009-09-18)
Children born after PGD as healthy as those born after conventional IVF treatment
Children born after embryo biopsy for preimplantation genetic diagnosis (PGD) do not show any more major malformations than those born after artificial reproduction technologies (ART) without PGD. view more (2007-06-18)
Making a face: A new and earlier marker of neural crest development
The fate of cells that go on to form the face, skull and nerve centers of the head and neck in vertebrates is determined much earlier in development than previously thought, and is independent of interaction with other forming tissues. view more (2006-07-12)
In-vitro fertilization improved with 3-D/4-D-guided embryo transfer and new placement target
Beverly Hills, Calif. and Washington DC (ASRM Annual Meeting) - October 15, 2007 - The pregnancy rate for patients undergoing in-vitro fertilization (IVF) is improved when doctors use advanced 3D/4D imaging to guide the placement of embryos to the point where the endometrium is most receptive to implantation. view more (2007-10-17)
Pregnant prehistoric fossil offers clues to past
University of Alberta scientists have named a new species of ancient marine reptile, fondly called the Ping Pong Ichthyosaur for the spot the prehistoric creature called home for the last 25 years. view more (2006-09-22)
Female human embryos adjust the balance of X chromosomes before implantation
Dutch researchers have found the first evidence that a process of inactivating the X chromosome during embryo development and implantation, which was known to occur in mice but unknown in humans, does, in fact, take place in human female embryos prior to implantation in the womb. view more (2009-06-30)
Center releases new public survey on stem cells
Stem cells are unique among human cells in that they possess the uncanny ability to develop into virtually any other cell of the body, offering a hypothetical tool kit for repairing diseased hearts, mending broken spinal cords, or correcting genetic diseases, among other hoped-for benefits. view more (2005-10-14)
New test can detect both genetic and chromosomal abnormalities in embryos
One-step screening for both genetic and chromosomal abnormalities has come a stage closer as scientists announced that an embryo test they have been developing has successfully screened cells taken from spare embryos that were known to have cystic fibrosis. view more (2009-06-30)
